Posture, flexibility and grip strength in horse riders

Area of Science:

• Equine biomechanics
• Sports science
• Rider physiology

Background:

• Rider asymmetry is a recognized negative trait, potentially impacting horse training and performance.
• The origins of acquired postural and functional asymmetry in riders are multifactorial and not fully understood.
• Ambidextrous horse training is desirable, making rider symmetry important.

Purpose of the Study:

• To assess postural, strength, and flexibility symmetry in a large rider population.
• To determine if specific rider traits develop due to riding experience and competition level.
• To investigate the relationship between years of riding, competition level, and rider asymmetry.

Main Methods:

• 127 right-handed riders were categorized by years of riding and competition level.
• Measurements included leg length, grip strength, and spinal posture by a physiotherapist.
• 3-D motion capture technology assessed standing/sitting posture and trunk flexibility.

Main Results:

• Significant anatomical asymmetry was observed in acromion process height related to competition level (p=0.048).
• Sitting iliac crest height showed significant asymmetry related to years riding (p=0.021).
• A significant interaction between years riding and competition level was found for lateral bending range of motion (p=0.047).

Conclusions:

• Higher competition levels in dressage may predispose riders to increased risk of asymmetry.
• Riding demands might lead to asymmetry and potential chronic back pain rather than improved symmetry.
• Further research is needed to fully understand the long-term effects of riding on rider biomechanics.
